"I am coming back from the high, blue building."

Translation: Visszajövök a magas, kék épülettől.

I know that "A magas, kék épülettől jövök vissza" (which was marked wrong and which I reported) changes the emphasis/focus to the building, but isn't that a possible reading of the English sentence?

Yes, absolutely.
As an answer to "Where are you coming back from?".

Thanks. Glad I reported it.
